| Abstract: | Safflower yellow was extracted by ultrasound -assisted method and extraction concl~tlons were optimized by single factor and orthogonal experiment. Stability of safflower yellow under UV ir- radiation, pH, metal ions and temperature was investigated. The results showed that the optimum con- ditions for extraction of safflower yellow pigment：ultrasonic power 80 W, ultrasonic time 40 min, ul- trasonic temperature 45 ℃. Safflower yellow pigment has good thermal stability, acid resistance and UV resistance. |
| Keywords: | ultrasonic method safflower yellow stability extract |
